HASP-LOCK.

SPECIFICATION forming part of Letters Patent No. 447,698, dated March3,1891.

Application led May 1,1890. Serial No. 350,206. (No model).

To @ZZ whom it may concern.-

Be it known that I, WILLIAM W. PURsELL, a citizen of the United States,residing at Berwick, in the county of Columbia and State ofPennsylvania, have invented certain new and useful Improvements inStaple-Locks; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relatesl to locks which are especially constructed to beused in connection with and for fastening hasps.

The purpose of the invention is to provide a simple and compact lockwhich will be Water-proof, not easily picked7 and economical inconstruction.

The improvement consists of the novel features and peculiar constructionand combination of the parts which will be hereinafter more fullydescribed and claimed, and which are shown in the accompanying drawings,in Whioh Figure 1 is a front view showing the application of theinvention. Fig. 2 is a plan View of the lock and the key. Fig. 3 is aplan section and end view of the locking head or-cap. Fig. 4t is aviewof one half of the case or barrel and an end and side view of thekey-guide. Fig. 5 is a side and end view of the other half of thebarrel. Fig. 6 is a cross-section on the line X X of Fig. et of the oaseor barrel and an end view of the locking-guide. Fig. 7 is a perspectivefront and rear end view of the locking-bolt. Fig. 8 is an enlarged viewof the end of the barrel, showing the guide end of the locking-bolt inposition.

The barrel or case, which is preferably cylindrical in form for economyof construction, is made in two parts or halves A A', which are securedtogether in any convenient manner, preferably by providing each withlateral wings a a at one end, which wings are riveted together and forma stop to limit the movement of the lock when inserted in the staple C,as shown most clearly in Fig. 1. Each ot' the halves A A is providedwith stops b b', which are designed to enter notches on the edges of thekey B and permit a turnin g of the same when the notches in said keycoincide with the said stops. Obviously an endless number of locks maybe constructed, in which no two keys will be alike,` simply by varyingthe number and changing the position of the said stops b o. The stops inone half of the case may be located in the same or a different planefrom the stops b in the other half. It is preferred, however, to havethe said stops b b located at different positions, as it renders theloc-k more difficult to pick. The locking-bolt D is journaled in theAend of the case or barrel opposite that provided with the ears or wingsa a', and its outer end is hanged or provided with lateral projectionsd, for the purpose hereinafter more particularly described.

The shank d of the locking-bolt is iattened at its inner end and passesthrough a guide E, which is tted between the halves of the case and isheld in place by the lateral projections c, fitting in grooves d3,formed betweenthe said halves. This guide is adapted to have alongitudinal movement in the case and is pressed forward by the springF, which is mounted on the shaft d. This guide E serves to lock the boltD and hold it against rotation, and when pressed in by the key its projections e are disengaged from the said grooves in the case and comeopposite an enlarged part of the said case, thereby enabling the guideand locking-bolt to be turned.

The locking head or cap G is adapted to be fitted on the end of thebarrel or case and is provided on its inner side with the interlockingshoulder g, which is engaged by the flanged head or projections d of thelockingbolt and secures it in position. The projection H on the side ofthe case is constructed to enter a groove 7L in the said cap or head Gand hold the same against turning when placed on the said case.

The key-guide I is a disk having an annular iange t', which is fitted ina groove t" in the case or barrel, and has an opening to permit theinsertion of the key. The operation of the lock is as follows: Then thehasp is passed over the staple, the case, the lockinghead being removed,is passed through said staple and is held in place by adjusting the saidlocking head or cap on the end of the case which has been thrust throughthe staple and is secured thereon by turning the locking-bolt so thatits flanged ond will overlap IOO the shoulder g in the interior of thesaid cap or head, which is accomplished in the follow ing manner: Thekey slotted at its inner end is inserted in the case and pressed insufficient-ly far to bring the notches therein opposite the stops in thecase, and also carry the guide E into the enlarged portion of the saidcase, when on turning the said key the locking-bolt will be rotated onits axis and effect a locking of the said cap. lVhen the key iswithdrawn, the spring F will press the guide E back and lock the bolt.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. A hasp-lock comprising a case having a stop at one end to limit themovement of the lock when thrust through a staple, a rotatablelocking-bolt at the opposite end of the case, and a locking head or capsecured to the case by the said locking-bolt, substantially as setforth.

2. The combination, with the case and the rotatable locking-bolt, of thespring-actuated guide having engagement with and adapted to turn withthe said locking-bolt,but free to move thereon, and havinglateralprojections which are adapted to engage with the said case, and a capadapted to be engaged by the said locking-bolt, substantially as setforth.

3. The combination, With the case having a stop at one end to limit themovement ot' the case when thrust through a staple and a rotatablelocking-bolt in the case at the end opposite the said stop, havinglocking projections at its outer end, ot a locking-cap having an innertia-nge, and an interlocking groove and projection between the said capand case to guide the cap when placed on the ease to give properdirection to the lookin g-bolt head and prevent the cap from turningwhen in place on the case, substantially as described.

4E. A hasp-lock comprising a ease which is made in sections, eachsection having lateral Wings which form means for securing the saidsections together and serve as a stop to limit.

the movement of the said ease when thrust through the staple, alocking-bolt inclosed within said case and adapted to have a nievementto secure the lock when in position, and a cap held on the case by thelocking-bolt, substantially as set forth.

5. In a hasp-lock, the combination, with the case or barrel made insections, each section having stops, of a key having notches in itsedges to correspond with the position of the said stops, substantiallyas described.

6. The hereinbetore specified hasplock, composed of a case which is madein sections, each section having stops and lateral wings which serve asfastening' means for securing the sections together, a rotatablekey-guide I, the locking-bolt D, the guide E, mounted on the shank ofthe locking-bolt and having a limited movement thereon, the spring F,for pressing the guide E back in the ease, and the locking head or cap(l, substantially as set forth.

In'testimony whereof I affix my signature in presence of two witnesses.

WILLIAM lV. PURSELL.
